Specification of Letters Patent.

To all whom limo/y concern:

Be it known that I, HENRIK voN Comma, citizen of Sweden, residing at Stockholm, Sweden, have invented new and useful Improvements in Coverings for Milking Organs, of which the following is a specification.

The present invention refers to an improvement in coverings for milking organs especially in such coverings which consist of spon y caoutchouc or india rubber.

ti milking organs in milking machines with spongy caoutchouc so that the teats will be squeezed between the milking organs "in a soft and elastic manner without being damaged. Owing to its porous nature the sponvy caoutchouc however with eagerness will a sorb milk, with which it comes into contact during the milking operation, and such absorption will result in diiliculties of cleaning the milking organs.

'lhc presentinvention has for its object to obviate this inconvenience and consists 'III covering the spongy daoutchouc with a thin iilm of water proof material, for instance ordinary caoutchouc, such films being made sulllciently thick to prevent the soongy 'caoutchou'c from absorbing fluid, without diminishingthe elasticity oi the covering in any practical de ree.

For making the invention more fully understood the accompanying drawing illustrates a milking organ, comprising two plates, between which two teats smmltaneously are squeezed and the milking thus performed.

Figure 1 is a transverse section of the milking organ, and Fig. 2 a plan of the same.

.1 indicates a rectan ular casing without bottom and cover. Within the casing a plate 2 is movable to and fro in such a man nor that the teats during the forward movement of the late 2 are squeezed against the rear wall 3 o the casing, such squeezing taking place from the root of theteat downwarts to the lower part of the teat. '.lhe movement of a milking plate towards a stationary plate for-milking purposes is previously well known and need no further deseri tion, the more as it constitutes no part of t m present invention. The plate 2 and the rear wall 3 of the casing constituting the milking organs are covered with plates 4 and ms been held convenient to cover the.

5 made of s )ongy caootchoue. In order to obviate that said )lates and?) may obsorb milk with which they will come in contact during the milking operation, they are coated with a thin film 6 and Trespectively, which may extend round the plates so that all their side surfaces are coated by chouc has proved to be a suitable material-v Said coating may be fixed for this purpose. to the plates 4, 5 in any suitable manner and may also consist of an unpregnation of caoutchouc or the like on the sur aces of the plates 5.

8 and 9' indicate flexible. side walls connecting the milking organs laterally and adapted to prevent the tents from being casing 1 when being squeezed between the .plates 4. and 5.

The described manncrol' coating the coverings with a water proof material is employable not only for milking organs, comprising plates as described and shown, but nlso to every kind of milkingorgans, by means of which the milking operation is performed. The invention is therefore not limited to the milking organs shown.

Having now particitlarly described my invention and set forth in what manner the same is to be performed, it claimi- 1. in milking machines a spongy covering for the milking organs coated with at him of water proof material.

I pressed against the shorter side walls of the .2. 1n milking machines the combination plate, caoutchouc plates covering the insides of said milking organs, aml connected by lateral flexible side walls.

4. In milking mitt-limes a covering for the milking organs, comprising plates of spongy cmutchmui, cmted Wiflh & film of Water proof mmeria-i.

5. In milking macin'nes 3 covering for the nrgxms, cemprisiiig plates of spongy cmuncilouc, seated with a, film of WeltBI' proof material and cennected laterally by means of flexible side Walls.
